Similar reference characters refer to similar parts throughout the several views in the drawings.

Referring now to the drawing and more particularly to Figures 1, 2 and 3, a portion of the door is indicated at 10 and it is provided with an opening indicated at 11 preferably circular; a ring-like frame member generally indicated at 12 and preferably of substantially T-shaped cross section (see Fig ure 3) is made up of a plate-like member 13 adapted to rest fiatwise against the door or door panel and ring-like flange '14 which preferably snugly fits and projects through the opening 11. The plate-like member 13 and the ring member 1% are preferably integral and may be cast,-for example, in one piece, and it will be noted from Figure 3 that the plate member 13 projects to either side of the ring member 14. The plate member 13 is preferably extended to provide a suitable number of ears 15 (Figure 1) through which suitable securing means such as the bolt 16 may be passed to fasten the frame I member 12 to the door or door panel.

The plate member 13 is provided with an opening 17 preferably circular and this opening is provided with a suitable grating indicated at 18, the members or bars forming the grating 18v being preferably integrally formed with the frame member 12.

At its right-hand end, as seen in Figures 2 and 5, the frame member is provided with two spaced upstanding lugs or ears 19-20 which preferably fall within the compass of the ring member l l; the member 14 is cut away as at 21 and 22 (see Fi ure 5). At its left-hand side, as viewed in Figures 2 and 5, and as is better shown in Figure 4, the mem ber 14 is provided with an upstanding keeper 23 shaped substantially as shown in Figure 4. To the right of the keeper 23 the ring member is cut away as at 24 (see Figure 5).

A ring-like frame member 25 of L-shaped cross-section (see Figure 3) is adapted to be somewhat snugly received within the ring member 14 of the frame 12 and to rest against the plate member 13. The frame member 25 has mounted therein as by appropriate rivets 26 (see Figure 6) a non-breakable glass gcnerally indicated at 27. The glass 27 is preferably made up of two separate sheets 28 and 29 of glass between which is a sheet of celluloid 30 suitably connected to each glass'and preferably bonded thereto.

At its right-hand portion, as seen in Figure 6, the frame member 25 is provided with a pair of lugs 31 and 32 projecting away from the frame 25 and spaced and shaped so that their right-hand ends fit substantially into the slots 21 and 22 cut into the ring member 14, the lugs 31 and 32 being substantially alined with the lugs 19 and 20 respectively.

The left-hand portion of the frame member 25 (as seen in Figure 6) is provided with a rectangularly shaped projection 33 adapted to fit into the recess 24 (Figure 5) in the ring member 14 of the frame 12 and upon this portion of the frame 25 is mounted a latch generally indicated at 34 adapted to coact with the keeper 23.

The latch 34, shown in cross-section in Figure 8 on an enlarged scale, comprises preferably a hollow cylindrical member 35 pivotally mounted and secured to the frame 25, as is generally indicated at 36. The upper portion of the cylindrical member 35 is shaped to form a knob, as at 37, and is preferably knurled to permit ease of manual manipulation.

Near the lower portion of the cylindrical member 35 there is integrally formed therewith a projecting lug 38 adapted to form a latch for coaction with the keeper 23 on the frame 12. Housed within the cylindrical member 35 and supported thereby is a helical spring 39 having its upper end anchoredin the member 35 as by being passed into a small opening 40 provided therein. The lower end of the spring 39 is anchored to the frame member 25 as by passing the lower end into a suitable aperture 41 provided in the member 25, and through a slot in member 35.

As is shown in Figure 6, the cylindrical member 35 of the latch 34 is provided with a lug 42 projecting radially therefrom near its lower end (see also Figure 4) and in the frame member 25 is secured an upstanding pin 43 positioned in the path of rotary movement of the lug 42 about the axis of the member 35.

The spring 39 is tensioned so as to tend to rotate the latch 34 and hence the lug 38 in clockwise direction, as seen in Figure 6, the pin or stop 43 on the frame 25, coacting with the lug 42, acting to limit the extent of this rotary movement and to hold the lug 38 in substantially the position shown in Figure 6.

The frame member 25 is preferably of somewhat less thickness than the ring member 14, as viewed in Figure 3, and shaped to fit into the ring member 14 but to overlap its right-hand face is a small closure or door 44 preferably made of metal. The door 44 is of a generally circular shape and is provided at its right-hand portion, as seen in Figures 2 and 7, with a pair of upstanding lugs or cars 45 and 46 so spaced that they are alined with and received between the lugs 31' and 32 of the frame member 25, the latter lugs being in turn alined with and received between the lugs 19 and 20 of the frame 12. Through suitable alined openings in all of these alined lugs is passed a hinge pin 47 whereby the window frame 25 and the door 44 are coaxially hinged to theframe l2.

The door 44 is cut away as at 48 at its lefthand portion, as seen in Figure 7 (see also Figures 2 and 4) so that the door 44 clears the latch construction 34. A knob 49 preferably knurled is secured to the door 44 to permit manual manipulation thereof.

About the hinge pin 47 and extending therealong and between the lugs or cars 45 and 43 is a helical spring 50 having one of its ends extended to engage the ring member 14 of the frame 12 and having its other end extended toward the center portion of the door 44 and resting thereagainst. The spring 50 is tensioned so as to rotate the door 44 in a direction to cause the door to close.

Preferably, the knob 49 is constructed to coact with a latching mechanism for locking the door 44 in closed position. This latch,- ing mechanism may conveniently take the form shown in cross-section on an enlarged scale in Figure 9, it being noted that the door 44, near its left-hand portion as seen in Figures 2 or 7, is provided with a substantially cylindrical housing 51 preferably cast integrally with the door 44 and extending in a direction toward the cut away portion 48. The housing 51 is open-ended at its lefthand end and has slidably mounted therein a latch member 52, urged in a direction outwardly through the open end by a spring 53.

The housing 51 has a lengthwise extending slot 54 through which passes the shank of the knob 49 so that the shank may be secured to. the latch member'52. Thus, the latch 52 may be manually moved against the action of the spring 53.

The outer end of'the latch 52 overlaps the cut away portion 48 of the door 44 and is adapted to coact with a suitable keeper, the latter being conveniently formed upon the lower portion of the cylindrical member 35 of the latch 34 and conveniently taking the form of a bevelled flange 55 extending peripherally sufliciently about the member 35 so that a portion of the flange 55 1s always presented for coaction wlth the latch 52 even though the member 34 be manually rotated.

that many features of my invention may be achieved in practice without actually locking or latching the door 45 and that such features and advantages may be achieved by simply mounting the knob 49 directly upon the door 44.

Considering now the operation and use of this device, it is first to be noted that should occasion arise for the occupant of the room, apartment or house to see who is seekin admittance, the occupant first takes hold or the knob 49, moves the latter to disengage the latch 52, and opens the door 44 against the tension of the spring 50, the window frame 25 with the non-breakable glass 27 therein being l eld in secure closed and locked position by the interengagement of the lug 38 of the latch 34 with the keeper .40- There is thus afforded a clear view through the door, but while such a view is being taken the occupant is in entire safety and under appropriate protection. v

In the first place, the gratings 18 restrict the opening 17 so as to prevent any implement of substantial size from being passed therethrough while the non-breakable glass 27 prevents injury to the eye of the observer. Thus, even though the glass 27 might be cracked as by receiving a blow from the eX- terior, it will not shatter and scatter and thus the eye of the observer is fully protected.

Furthermore, the eye of the observer is protected against drafts. Also, the glass prevents any substance to be thrown through the opening.

Should the observer or occupant desire to communicate with the caller either by word of mouth or to receive from the caller papers or the like, the observer lets go of the door 44 by releasing the knob 49 and takes hold of the latch 34, operates the latter to disengage the lug 38 from the catch 23, and swings the window and its frame 25 open, thus carrying into open position also the door 44.

Through the openings intervening the gratings 18 conversation may be carried on or papers and the like passed through. Releasing the latch. 34 brings the spring 50 into ac tion which causes the prompt closing movement of the window and its frame 25, as well as of the door 44, the spring 50 having caused a latching of the door 44 to the member 35, when the door 44 was previously released. The parts are restored by the spring 50 into the position shown in Figures 2, 3 and 9. The lug 38 on the latch 34 snaps in behind the keeper 23, due to the yielding action of the spring 39, and the shape of the keeper 23, all as will be clear from Figures 4 and 8, and without permitting disengagement of the latch 52 from the keeper 53, whereupon the window frame 25 ith its non-breakable glass and door 44 are locked in closed position and the parts are in readiness for subsequent actuation.

It will thus be seen that there has been provided in this invention, a device in which the several objects above-mentioned, as well as many thoroughly practical advantages, are successfully achieved. It will be seen that the device is of simple construction and of thoroughly dependable action in use and that a high degree of safety and protection is dependably afforded. Moreover, it is to be noted that the device is of simple manipulation and is easily controlled with one hand. It will also be noted that the device is w ll adapted to meet the varying conditions of hard practical use.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
